Go to a high-street or online bookstore, and one can find numerous biographies written about Muhammad — the reputed founder of Islam — by the likes of Karen Armstrong and Tariq Ramadan. These works — generally apologetic in nature — wholly rely on the traditional Islamic accounts of the Prophet’s life, and if they ever delve into the question of the reliability of those sources, it is only in the hope of explaining away incidents in Muhammad’s life that might come across as unsavory to modern readers.
